What ? Why didn't you order the Russian one ?? Would have saved you a lot of cash plus....and I think it's better...
Sorry, I have made some videos before but turned out I talk TOO much

It is also VERY hard to do sample measurements while holding the camera showing the result. I need a stand but don't have one...
I'll be doing of combo of text, pics and some videos because else the vids become too long.
Anyway. The short answer to: do I need this ? Yes !
Of course, you can go about and replace every cap you find around. That will also work of course. But if you're curious like me and don't believe the "howling wolves" just because they "howl", or if you don't believe every old cap is bad just because it's old and want to save time & money then this shouldn't fail in your tool bag....
I will open a new thread about this meter in the Technical Area.
